MD5密码怎么设置使用?



用户登陆


 
  $_COOKIE[name]=$_POST["name"];
  $_COOKIE[password]=$_POST["password"];
 

 if ($_COOKIE[name]=="" or $_COOKIE[password]==""){
echo "
用户名或密码不能为空,请重新登录!
";
exit;
}
  
 if($info['username']!=$_COOKIE[name]){
 echo "
该用户不存在!请重新登录!
";
 }
 else{
  if($info['userpass']!=$_COOKIE[password]){
 echo "
密码输入错误!请重新登录!
";
}

 else {

  echo "";
  exit;
  }
 }
 
?>



上面的是一个简单登陆动作的PHP,当然,再之前有输入文本框和登陆按钮,那个PHP就不发了。我想用MD5设置用户名和密码,加上
$set[name]="202cb962ac59075b964b07152d234b70";//设名字为123
$set[password]="202cb962ac59075b964b07152d234b70";//设密码为123
可是输入密码的时候就提示错误,我试了好久都不行,现在没加上$set[],所以想问高手怎么设置MD5,谢谢了。

------解决方案--------------------
验证时你是怎么比对的
------解决方案--------------------
加在哪? 没看懂你想要干什么?
------解决方案--------------------
$info['username']和$info['userpass']是从数据库中取出的数据吗?

用$info['username']和$info['userpass']与你登录时填写的姓名$_COOKIE[name]和密码$_COOKIE[password]进行比对吗?

如果数据库中保存的username和userpass是用MD5加密过的,那么在进行比对的时候将你填写的姓名与密码也MD5加密。

if($info['username'] != MD5($_COOKIE['name'])){
echo "
该用户不存在!请重新登录!
";
}else{
if($info['userpass'] != MD5($_COOKIE['password'])){
echo "
密码输入错误!请重新登录!
";
}else{
echo "";
exit;
}
}

------解决方案--------------------
在数组库的用户表里面,密码字段采用md5加密,然后登录的时候把用户输入的密码加密和数据表里面的密码进行比对就可以了啊!希望我理解的意思是对的!

What are some common problems that can cause PHP sessions to fail?What are some common problems that can cause PHP sessions to fail?Apr 25, 2025 am 12:16 AM

Reasons for PHPSession failure include configuration errors, cookie issues, and session expiration. 1. Configuration error: Check and set the correct session.save_path. 2.Cookie problem: Make sure the cookie is set correctly. 3.Session expires: Adjust session.gc_maxlifetime value to extend session time.

How do you debug session-related issues in PHP?How do you debug session-related issues in PHP?Apr 25, 2025 am 12:12 AM

Methods to debug session problems in PHP include: 1. Check whether the session is started correctly; 2. Verify the delivery of the session ID; 3. Check the storage and reading of session data; 4. Check the server configuration. By outputting session ID and data, viewing session file content, etc., you can effectively diagnose and solve session-related problems.

What happens if session_start() is called multiple times?What happens if session_start() is called multiple times?Apr 25, 2025 am 12:06 AM

Multiple calls to session_start() will result in warning messages and possible data overwrites. 1) PHP will issue a warning, prompting that the session has been started. 2) It may cause unexpected overwriting of session data. 3) Use session_status() to check the session status to avoid repeated calls.

How do you configure the session lifetime in PHP?How do you configure the session lifetime in PHP?Apr 25, 2025 am 12:05 AM

Configuring the session lifecycle in PHP can be achieved by setting session.gc_maxlifetime and session.cookie_lifetime. 1) session.gc_maxlifetime controls the survival time of server-side session data, 2) session.cookie_lifetime controls the life cycle of client cookies. When set to 0, the cookie expires when the browser is closed.

What are the advantages of using a database to store sessions?What are the advantages of using a database to store sessions?Apr 24, 2025 am 12:16 AM

The main advantages of using database storage sessions include persistence, scalability, and security. 1. Persistence: Even if the server restarts, the session data can remain unchanged. 2. Scalability: Applicable to distributed systems, ensuring that session data is synchronized between multiple servers. 3. Security: The database provides encrypted storage to protect sensitive information.

How do you implement custom session handling in PHP?How do you implement custom session handling in PHP?Apr 24, 2025 am 12:16 AM

Implementing custom session processing in PHP can be done by implementing the SessionHandlerInterface interface. The specific steps include: 1) Creating a class that implements SessionHandlerInterface, such as CustomSessionHandler; 2) Rewriting methods in the interface (such as open, close, read, write, destroy, gc) to define the life cycle and storage method of session data; 3) Register a custom session processor in a PHP script and start the session. This allows data to be stored in media such as MySQL and Redis to improve performance, security and scalability.

What is a session ID?What is a session ID?Apr 24, 2025 am 12:13 AM

SessionID is a mechanism used in web applications to track user session status. 1. It is a randomly generated string used to maintain user's identity information during multiple interactions between the user and the server. 2. The server generates and sends it to the client through cookies or URL parameters to help identify and associate these requests in multiple requests of the user. 3. Generation usually uses random algorithms to ensure uniqueness and unpredictability. 4. In actual development, in-memory databases such as Redis can be used to store session data to improve performance and security.

How do you handle sessions in a stateless environment (e.g., API)?How do you handle sessions in a stateless environment (e.g., API)?Apr 24, 2025 am 12:12 AM

Managing sessions in stateless environments such as APIs can be achieved by using JWT or cookies. 1. JWT is suitable for statelessness and scalability, but it is large in size when it comes to big data. 2.Cookies are more traditional and easy to implement, but they need to be configured with caution to ensure security.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
